you can order the choke knob separately.

In case I wasn't clear, it's not the knob that gives me an headache. When I bent the axle the knob is on it, it first couldn't go in. After I straitened it up now the choke doesn't stay out.

I tried and wasn't successful. I don't know what to look for.

Short piece of tubing, slotted, fit on the shaft, keep knob out,, shorter piece = 1/2 choke. Anything you can slip in there,, or, buy parts and hope you can get in and back out and not mess up the carb..

Does anyone know what mechanism provides detent to the plunger?    

I see a lot of inexpensive "plunger caps" for sale.  

EDIT: After a little searching it appears that the cap assembly is the detent.  There are two parts.  The threaded plastic part and a rubber grommet.  I think the plastic provides the detent and the rubber cap applies the pressure needed to hold the detent.

I found a video that shows how you can "fix" the issue with a zip tie around the rubber grommet. I applied pressure with my finger and it improved the detent.

I'll try the zip tie trick.  If it works I'm going to explore replacing the plunger cap.  

Here is the video.  (Some of you might find it entertaining.)

IDK how well it works but there are YouTubers out there who make knobs using hot glue. I saw some pretty good looking ones. If you have a favorite beer,A bottle cap can be built in.
One guy used a box end wrench for the form and made it easy to twist.
I know, twisting isn't the goal here,just saying.

After I did the cam,exhaust and jetting it took mine a little over two miles to be able to ditch the choke, Or,I could reach down and crank the idle up. After I figured that out I just fired it up on the choke, jacked the idle,rode off and kept backing the idle down as it warmed up. Didn't matter if it was a pretty day or a crisp morning, first start required some attention.
